A great, wholesome family meal, Chicken Veggie Rice Casserole uses precooked chicken to cut down on prep significantly. The tasty variety of flavors, colors and textures makes this tasty, one-dish dinner a winner every time!

Chicken Veggie Rice Casserole has many basic, staple ingredients that come together nicely to create a great meal. Cooked rice and leftover/precooked chicken are mixed with diced green peppers, onions, celery and pimentos for a colorful, textured variety.

Rather than using a can of condensed soup (as found in many casseroles), we make our own sauce with a bouillon packet, seasonings and mayo (trust me, it works). And of course this casserole wouldn't be complete without some buttered breadcrumbs on top! Yum!

Why you'll love it

Prep time cut in half- Precooked chicken makes this meal a breeze. After you chop the veggies and cook the rice (heck, you could even use instant if you wanted to), there's not much more to it--other than mixing a few extras, making the topping (which is super easy) and popping it into the oven.

Low maintenance- It doesn't get much easier than this. Isn't that the true beauty of a casserole? Once the work is done, it bakes in the oven and leaves you alone until the timer goes off, giving you ample time to catch up on your favorite Netflix show!

Highly customizable- Love different kinds of peppers?--Add some. Big on seasoning?--Toss more in. Like wild rice instead?--Swap it. I think you get the idea.
chicken veggie rice casserole ingredients

Ingredients

  • cooked rice- I typically use long grain white rice, but wild rice would also be good in this
  • precooked chicken- may also use rotisserie or leftover turkey
  • green pepper
  • onion
  • celery
  • diced pimentos- for added color and taste
  • 1 packet granulated chicken bouillon- equivalent to 1 cube; I like buying it this way because you don't have to break it up

  • salt and pepper
  • butter
  • Italian bread crumbs- feel free to use plain
